ACPL-W341-500E

Overview

The ACPL-W341-500E is a single-channel IGBT gate drive optocoupler from Broadcom's ACPL series. It features a GaAsP LED optically coupled to an integrated circuit with a power output stage, housed in a surface-mount SO-6 stretched package. The device provides high-speed response and ultra-high common mode rejection. Key electrical parameters include a maximum forward voltage of 1.95V, a typical rise time of 43ns, and a typical fall time of 40ns. It offers an isolation voltage of 5000Vrms and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Integrated power output stage designed for direct driving of IGBTs and MOSFETs
• Ultra-high common mode rejection capability for noise immunity
• Bootstrappable supply current architecture for flexible gate drive configurations

Applications

• Isolated IGBT and power MOSFET gate drive circuits
• AC and brushless DC motor drives
• Industrial inverters and home appliance inverters
• Switching power supplies (SPS)

Procurement Notes

Verify the specific suffix '500E' against official datasheets to confirm insulation ratings and safety approvals. Ensure the ordered component matches the required SO-6 stretched package dimensions. Cross-reference manufacturer part numbers with authorized distributor catalogs to avoid counterfeit components. Confirm RoHS compliance status as per current regulatory standards before final procurement.

Selection Notes

Select this component when high-speed isolation and robust gate drive capability are required for power electronics. The 5000Vrms isolation rating suits applications demanding strict safety separation. Consider the 43ns rise time for switching frequency requirements. Evaluate the stretched SO-6 package for PCB layout constraints compared to standard packages. Verify input current specifications match the control logic levels.

Part Context

This device belongs to the Broadcom ACPL series of optocouplers, specifically engineered for power management and motor control applications. The series emphasizes reliability and high performance in industrial environments. The ACPL-W341 variant distinguishes itself through its enhanced isolation voltage and integrated output stage, differentiating it from standard logic output optocouplers in the same family.
